Specification of Letters Patent.

Patented Apr. 16, 1918.

Application filed March 18, 1514. Serial No. 825,691.

To all whom, it may concern:

Be it known that I, HENRY GIBSON ONnILL, a citizen of the United States, residing at the borough of Manhattan, city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Engine Starting and Pumping Apparatus. of which the following is a specification, reference being had therein to the accompanying drawings, forming part thereof.

My invention relates to pumping apparatus. more particularly to pumping apparatus installed on automobiles or motor cars for supplying compressed air for tire inflation or for other purposes.

Objects of my invention are to combine such a pumping apparatus with an electrical equipment emp oycd for starting an internal combustion engine or for other purposes, and to combine the pumping apparatus and the engine-starting apparatus in a unitary construction which shall be simple and compact, highly effective in all its functions, durable, reliable, accessible, cool in operation, neat and symmetrical in appearance, inexpensive to manufacture and install, and convenient to install. A further object is to produce such a combined apparatus particularly adapted to be applied to automobilcs which have been built without provi- .ion having been made for its accomm0dation. and also well adapted to be supplied as equipment on new cars without alteration or rc-arrangement of any vital or important parts of the car as previously built without such equipment, and to produce such a combined apparatus suitable for installation at the front of the car. ()ther more particular objects and advantages of my invention will hereinafter appear.

My invention includes a pumping device arranged to be operated through two sets of gearing, one of these being a set of speedn'uiltiplying gearing pertaining to both the electrical apparatus and to the pumping device. and the other being a set of speed-reducing gearing for the pumping device. My invention also includes novel pumping apparatus particularly adapted to be and effectively combined with the electrical apparatus. My invention further includes a number of features of construction and combinations of parts, as will appear from the following description.

I shall now describe the combined pumping and electrical apparatus embodying my invention illustrated in the accompanying drawings and shall thereafter point out my invention in claims.

Fig. 9 is an end elevation of two of the cooperative centrifugally-operated clutch disks or plates. I

The mechanism of the apparatus is inc-losed in a symmetrical casing, shown as made up of a lar er or main part 1 having right and left cyllndrical shell portions and a central portion connecting the shell portions, a rear middle part 2, and end caps and 4; all parts of the casing being rigidly joined to form a strong and rigid combined casing and supporting frame, the end caps 3 and 4 being shown as provided with lugs for bolting to the side frame of an automobile chassis at the front of the engine.

In the present invention the pumping device, an electrical power device and operating mechanism are so combined that parts of the operating mechanism are common to both the pumping device and the electrical device, and of the remaining parts, some belong or pertain particularly to the pumping device and others particularly to the electrical device.

The combined apparatus has a central shaft 5, which ma be an integral portion of the engine sha t, or it may be a short shaft coupled to the engine shaft in axial alinement therewith, probably usually the latter, for greater convenience in installing the apparatus. An engine-connected member, shown as a bevel gear 6, is fixed on the forward end of the central shaft 5 and meshes with a bevel pinion 7. The bevel pinion 7 has a permanently locked enga ement with a flanged journal sleeve 8, as y means of interengaging teeth or projections, as best appears in Fig. 1. The sleeve 8 1s journaled in a bearing 9 in the casing and its flange or disk portion is secured t0 a gear frame 10, shown as rigidly formed 1n a single piece, as will appear by comparing Figs. 5 and 6. A hub or boss 11 1s secured to the other side of the gear frame 10, being shown in Fig. 5 as having an enlarged or flange portion screwed into the end of the gear frame, and the hub 11 is shown as journaled in a ball bearing in a partition disk 12 in the casing. The flanged sleeve 8, the frame 10 and the hub 11 together form a rigid gearing carrier. The central shaft 5, the bevel gear 6, the bevel pmlon T and the gearing carrier are all in permanent operative connection with the engine and may be correctly considered as engineconnected parts or engine-connected members, although the centrally located bevel gear 6 will hereinafter be more particularly referred to as an engine-connected member. It will be apparent that, excepting for structural reasons, the bevel pinion 7 and the several rigidly joined parts 8, 10 and 11 of the gearing carrier could all be formed of a single or integral piece.

The bevel inion 7 is journaled on the armature sha t 13 of a combined electric generator and motor Ll, which for simplicity of terminolog is hereinafter referred to as a dynamotor and which occupies the c lindrical space in the casing appearing at tie right in Fig. 1 and which per .96 may be of any suitable construction. The armature shaft 13 extends transverse to the central shaft 5 and is shown as mounted in ball hearings in the end cap 1 at the right in Fig. 1, and in a supporting disk or trans verse Wall 15 in the casing at the other end of the dynamo-motor 1 and the armature shaft 13 is also journaled in the gear frame 10 of the gearing carrier, as appears in Fig. 5. The set of gearing comprising the bevel gear 6 and the bevel pinion 7 constitutes speed-multiplying gearing from the engine to the dynamo-motor 14 and from the engine to the pumping apparatus, and constitutes speed-reducing gearing from the dynamomotor 1 1 to the engine. The ratio of this gearing illustrated in the drawings is three to one when operating as speed-multiplying gearing, which, of course, becomes one to three when operating as speed-reducing gearing.

The pumping device is arranged to be operated, through manually controlled clutching means, from the hub 11 of the gearing carrier, which, in the pumping operation, is rotated from the engine by means of the bevel ear 6 and bevel pinion T. The pumping evice and speedreducing gearing therefor are located in the cylindrical space in the casing at the left of the partition 12, as appears in Figs. 1 and 5.

A worm or spiral pinion 16 is arranged in axial alinement with the gearing carrier and bevel pinion 7. At its end ad acent to the gearing carrier the spiral pinion 16 is shown as provided with a bearing, into which a reduced end portion of the gearing carrier hub 11 is received to rotatively support the spiral pinion at that end. The other end of the spiral pinion 16 is reduced to form a journal, which is supported in a bearing carried by a gearing support or frame 17 The spiral pinion or worm 16 engages a spiral gear or worm wheel 18 having slightly reduced concentric end portions 1ournaled in the support 17, and these concentric end portions of the spiral gears 18 carry crank-pins 19. The axis of the spiral gear 18 is transverse to the axis of the spiral pinion 16, and the spiral gear 18 is shown as located below the spiral pinion 16. The Worm gearing or spiral gearing illustrated in the drawings efiects a speed reduction of one to four in the operation of the pump.

A pair of pump cylinders 20, shown as supported by a bracket piece 21, are arranged obliquely to the axis of the spiral pinion 16, and extend partly above and partly below a horizontal plane coincident with the axis of the Worm 16, and are in parallel relation, one at each side of a vertical plane coincident with the axis of the spiral pinion 16. The cylinders 20 contain reciprocative trunk pistons 22, connected to the crank-pins 19 by piston-rods 23, to be reciprocated thereby. The inclined or oblique arrangement of the pump cylinders 20 and the spiral gearing as arranged contribute much to compactness of construction and utilize the available space in the casing to the best advantage. An outlet or eduction pipe 24 extends to the outside of the casing through a closure plate 25 of the end cap 3 from a valve chamber 26 common to both pump cylinders 20, and the pump valves, not appearing in the drawings, may

be of any suitable construction, as is well the journal hub 11 of the gearing carrier to 1,2eae91 operate the pump from the engine. The journal portion of the hub 11 projects from its hearing and carries a clutch member 27 splined thereon and having inclined clutch teeth ad acent to the Worm 16, which is of enlarged diameter at that end and provided with inclined clutch teeth cooperative with those of the clutch member 27. The slidable clutch member 27 is operated by a clutch lever 28 shown as pivoted on the partition disk 12.

A rack guide 29 is secured in the upper part of the casing and guides a rack 30, which is connected to the clutch lever 28 by a rod 31 guided by an abutment head 32 carried by the rack guide 29. A coiled thrust spring 33 surrounds the rod 31 between the abutment and the rack 30 and will shift the clutch member 27 to the disengaged position shown in the dmwings and maintain it there. A key 34;, the end portion of the stem of which is a small pinion, may be inserted from outside of the casing through a suitable opening therein and into a corresponding opening or key-hole in the rack guide 29, the pinion teeth of the key 3 1 then engaging the rack 30 (compare Figs. 1 and 5).

By manually rotating and holding the key 3i, the clutch teeth of the clutch member 27 will be engaged with the clutch teeth of the spiral pinion or WOI'lIl 16 and the hub 11 of the gearing carrier Will be rotatively connected to the spiral pinion 16, so that the latter may be rotated from the former. It Will be understood that the pump can now be operated from the engine through the bevel gear 6 and bevel pinion 7, operating as speed multiplying gearing at the ratio of three to one, and through the spiral pinion 16 and spiral gear 18, operating as speedreducing gearing at the ratio of one to four, the combined action of the two sets of gearing efiiecting a speedreduction from the engine to the pump in the ratio of three to four, or three-fourths to one, which has been found to be a desir able ratio. The small diameter of the high speed intermediary pinions 7 and 16 assists to compactness of the apparatus and also provides for the employment of the spiral or worm gearing for operating the pump, such gearing advantageously combining with the pair of obliquely arranged pump cylinders :20, as hcrcinbefore described. Furthermore, the power-transmitting gearing carrier, the bevel pinion 7 and the bevel gear 6 all form parts of th electrical apparatus as well as of the pump, and all parts of the pumping apparatus and electrical apparatus are effectively combined.

The end portion of the dynamonnotor armature shaft 13 journaled in the gearing frame 10 has teeth thereon forming a small pinion 35 within the gearing carrier which extends freely into a hollow or cavity in the enlarged portion of the hub ll of the gearing carrier. The small pinion 35 of the armature shaft 13 meshes with one or more, shown as three, planetary gears 36 mounted, by means of journal pins 37, in the gear frame 10 of the gearing carrier. etary gears 36 mesh with an internal gear or internal-toothed ring 38 shown as rigidly secured by means of tap bolts 39 to a shell or gear-inclosing case 40 and to a pawl-carrying locking ring 41. The shell 40 and the locking ring it are rotatively mounted or journaled on the gear frame 10 at the right and left, respectively, as appears in Fig. 5. A stationary ratchet ring 42 is fixed on the partition disk 12 and is engaged by pawls $3 pivoted on the locking ring 41 and lightly pressed to engaging position by springs M (Fig. 8). The ratchet ring 42 the pawls i3 are arranged to lock or anchor the internal gear ring 38 in the direction of torque corresponding to an engine-starting operation.

In effecting an engine-starting operation, the dynamo-motor 14: is operated as a motor, the direction of rotation of the armature shaft 13 being clockwise as viewed from the left in Figs. 1 and 5, and as indicated by the arrows in several figures of the drawings. In the engine-starting operation, the gear ring 38 will be held stationary by the pawls i3 engaging the stationary ratchet rin 42 and rotation will be imparted to the gearing carrier, including the gear frame 10 and flanged journal sleeve 8, at a greatly reduced rate, the ratio of this reductlon in the construction illustrated in the drawings being about one to ten. The flanged sleeve 8 of the gearing carrier being permanently locked to the bevel pinion 7, as hereinbefore de scribed, the engine will be started from the dynamo -motor 14: through the planetary speed-rechicing gearing and through the bevel gearing 6 7 operating as speedreducing gearing, the total speed reduction being at the ratio of about one to thirty, but obviously it could be substantially anything desired.

lVhen the engine starts, its speed accelcrates. and rotation at an increased rate is imparted to the gearing carrier in the same direction as was its movement in starting the engine. The direction of rotative thrust or torque now being reversed, the pawls 3 will release to permit the gear ring 38 and its adjuncts to rotate with the gearing can ri'elr. The clutch member 27 may now be moved into engagement with the clutch teeth of the Worm or spiral pinion 1G, by means of the manual key 34, to effect the operation of the pump from the engine through the bevel gearing and the spiral gearing, as hereinbefore described.

Means are provided for connecting the The plangearing carrier directly to the armature shaft 13 to operate the dynamo-motor 14 as a dynamo without the operation of the planetary gearing. The hub 11 of the gearing carrier has the outer portion of its cavity enlarged, so as to provide a shoulder, and within this enlarged portion of the cavity rotatively carries a plurality of sheet metal clutch plates or clutch disks 45 having projections slidable in keyways or grooves with in the hub 11 gFigs. 5 and 9). Similar cooperative clutc 1 plates or disks 46 are rotatively carried by the extended end portion of the armature shaft pinion 35, being provided with internal teeth engaging or interlocking with the spur teeth of the pinion 35 (Figs. 5 and 9), so that the plates 46 are slidable longitudinally of the pinion 35. The clutch plates 45 and 46 are arranged in alternate relation, as appears in Fi 5, and a thrust ring 47 is shown as place beyond the clutch plates so that all of the clutch plates 45 and 46 will be between the thrust ring and the shoulder of the hub 11 at the bottom of the enlar ed portion of its cavity. Thrust pins 48, s own as three in number, guided in the gearing frame 10, are operated by a corresponding number of centrifugal weights 49 pivoted 1n the gear frame 10, to clamp together the clutch plates 4:5 and 46 and lock or rotatively connect the hub 11 of the gearing carrier to the pinion 35 of the armature shaft 13, so that, through readily traceable connections hereinhefore described, the armature shaft 13 will he rotated by the engine at the speed of the bevel pinion 7 and without the operation of the planetary gearing, the gear rln 38 and connected parts now rotating idly with the gearing carrier.

Under self-actuation of the engine, the rotative speed of the gearing carrier is sufficient to cause a firm gripping and frictional locking of the clutch plates 45 and 46, by reason of the centrifugal force developed in the weights 49; but at the much lower rotative speed of the gearing carrier in the engine-starting operation no such gripping action is developed and the clutch plates 45 and 46 may relatively rotate, the gear ring 38 then being locked against rotation by the pawls 43, as hereinbefore described. Also it should be noted that when the gearing carrier is rotated in the operation of the dynamo-motor 14: as a dynamo, the pawls 43 will be thrown clear of the ratchet teeth of the ratchet ring a2 by centrifugal force, so that there will be no clicking of these pawls on the ratchet teeth. It is to be observed that the dynamo-motor 14 will be operated as a dynamo from the engine through the bevel gearing 67 operating as speed-mult1plying gearing at the ratio of three to one, and without the operation of the planetary gearing, the several parts of which now rotate together without relative movement.

\Vhen the dynamo-motor 14 is operated as a dynamo, the electrical energy generated is stored and utilized to operate the dynamomotor as a motor in the engine-starting operation. Also it is to be understood, in accordance with common practice, that such electrical energy, either stored or taken directly from the dynamo motor ll operated as a dynamo, may be used for other than engine-starting operations. Any suitable regulating, controlling and indicating devices or instruments may be included in the electrical equipment, as is well understood in the art.

Obviously the construction permits the dynamo-motor to be used as a power device for driving the pump and this could be accomplished without serious added power consumption arising from the engine connection by permitting the engine to run idly with the pet cocks of its cylinders open to relieve compression.

Means are provided for manually starting the engine in the usual way in case any of the parts of the apparatus concerned in the engine-starting operation should get out of order. The bevel gear 6, back of its bevel teeth, is provided also with spur teeth, forming a spur ear in one piece with the bevel gear. Anot er spur gear 50 meshes with the spur teeth of the gear 6 and is fixed on a short shaft 51 journaled in the casing and which projects forward to the outside of the casing below the armature shaft 13, for the application of a usual crank.

It is to be noted that the weight of the combined pumping and electrical apparatus is substantially the same at each side of the central shaft 5, and that the apparatus is of symmetrical appearance. The arrangement of the pumping device with its set of speedreducing gearing and the set of planetary speed-reducing gearing employed in startmg the engine, at one side of the central shaft 5 and the dynamo-motor 14 at the other side of the shaft 5, with the set of gearing common to the dynamo-motor and to the pumping device placed at a middle position, is involved in the effective combi nation of the several parts of the unitary apparatus.

It is obvious that various modifications may be made in the construction shown in the drawings and above particularly described withln the principle and scope of my invention.
